What the heck is the > point of this track? None. Most positions on an audio CD are specified as sector numbers. The Red Book says that the start of the first track is at sector 0; the table of contents is placed in the lead-in area in sectors -32 to -1. Some CDs (and/or some CD drives) get something wrong so that the first track is reported to start at sector 32. One sector is 1/75th of a second (588 frames), so usually nobody notices this. > File : track00.cdda.wav Data before the first track is grabbed as "track 0" which doesn't ordinarily exist on audio CDs. > Frames : 5880 This is 10 sectors, not 32, so the explanation above doesn't apply. ;-) HTH Clemens
